I'm trying to model a parametric simple unit in Revit. So, I decided t use the generic family template. I want to model a rectangular unit with exterior wooden wall and interior steel frame. I have three problems 1- I have imported structural column profile into the family, but my problem is that I cannot align the section to two reference line. For example, I want to align the top of the column to the top exterior wall, and align the left side of the column to the left exterior wall; but I can just assign of these sides. 2- I've imported structural framing family in my generic model, but I cannot assign a parameter to the length of the beam, and the length is constant, and I can change the length just in 3D view. Do you know how to assign a parameter to the length? 3-I couldn't use the predefined walls it the family, so, I used extrusion. But I couldn't use the Revit windows family on the extrusion walls. Is there any way to use the predefined wall systems in Revit to be able to use the windows families?I'll appreciate if somebody help me on these.

I don't think you will be able to do what you are trying to do in a 'family' file. What you are trying to accomplish is do-able however.

Use an external parametric conceptual mass family to drive the geometry within a project file. Update the conceptual mass paramters and then 'update to face' for the walls etc.

I have made this work with reasonable success. Below is a video series on the process using a Garage as the sample building unit. The massing approach has changed a little but the process and concept is the same.
